Wild Ptooie Piranhas reappear in Yoshi's Woolly World, acting fairly similarly to previous games. However this time, when they are hit with a yarn ball they do not change to a different colour.[3] Their projectiles (Pokey Poms and Shy Guys) also roll along the ground.

Their name seems to suggest that they're related to Ptooies (another type of Piranha Plant), but it is unknown whether they are or not.
